You’ve earned the right to explore new places and meet new people! We’re here to make sure your journey is safe, smooth, and always first class. Entegra Coach and Spartan RV Chassis, your co-pilots on the adventure of a lifetime.

Entegra’s Anthem is built on the Spartan K2 450 chassis and is available in a 42’ or 44’ length. Designed, engineered, and made in America with the finest components creating a premier foundation for the most discerning RV makers and owners.

Spartan RV makes the only chassis built exclusively for motorhomes. We didn’t take the easy route and modify a truck chassis for our partners at Entegra. We knew they wanted an unmatched ride that was as smooth and quiet as it was invigorating and well-appointed. So, we built them the unique K2 450 chassis from the ground up. The highest-quality materials provide reliability and dependability, along with nationwide service, and the best warranty in the business.

Motorhomes riding on a Spartan RV chassis are built with care to stay on the road for a good long time.

Safety Innovations

Spartan Advanced Protection System – Anthem

Spartan Advanced Protection System® is the industry’s first and only comprehensive safety system engineered to keep your Entegra Anthem on the road, and safe… to enjoy every adventure.

  • Spartan Safe Haul™ The industry’s only factory-chassis integrated air supply for tow vehicle brake systems.
  • Automatic Traction Control (ATC) helps the driver maintain traction under the drive axle tires in slippery conditions by automatically applying brakes on the wheel end that is slipping. This helps transfer power to the wheel end with more traction.
  • Tire Pressure Monitoring System (TPMS) displays tire pressure and temperature for individual tires. The system will alert the driver if any tire pressure or temperature
    exceeds set thresholds. The system is expandable to monitor towed vehicles as well.
